Abstract

The invention provides a vibration generation method and device based on an audio signal, electronic equipment and a storage medium, and the method comprises the steps: obtaining the audio signal; detecting the real-time intensity of the audio signal and the mean value intensity in the current sampling process; determining the audio intensity relative break variable of the audio signal in the current sampling process according to the real-time intensity and the mean value intensity; and if the audio intensity relative break variable is greater than or equal to a preset threshold value, generating a preset vibration signal according to a preset rule. According to the invention, rhythm detection can be carried out in real time and the vibration waveform is synchronously generated.

Description

technical field [0001] The technical field of vibration driving of the present application specifically relates to a vibration generation method, device, electronic equipment and storage medium based on audio signals. Background technique [0002] Linear Resonant Actuator (LRA) is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. It is usually driven by alternating current, and the energized coil is subjected to ampere force in a magnetic field to drive the motor. vibration. In recent years, linear motors have been widely used in various vibration occasions of consumer electronics, especially games and AR / VR products, due to their advantages of strong vibration, richness, crispness, and low energy consumption. [0003] In order to enhance the user experience of games and AR / VR products, developers usually convert the input audio and other signals to generate the vibration drivin...
